Why Choose Liquid Rubber for Your Planter Boxes?

Liquid Rubber is not just a waterproofing solution; it's a way to ensure that your garden remains a vibrant, healthy, and beautiful space. With Liquid Rubber, you can focus more on enjoying your gardening and less on the maintenance of your planter boxes.

  • Long-Lasting Protection: Liquid Rubber creates a durable, waterproof barrier that significantly extends the life of your planter boxes. This protective layer shields the wood, concrete, or metal from moisture, reducing the risk of rot, decay, and rust.

  • Superior Flexibility: One of the standout features of Liquid Rubber is its ability to flex and move with your planter boxes. This flexibility is crucial in outdoor environments where temperatures fluctuate, ensuring the sealant does not crack or peel over time.

  • Eco-Friendly and Plant-Safe: Our commitment to the environment and your garden's health is reflected in our product formulation. Liquid Rubber is non-toxic and eco-friendly, making it safe for use around all types of plants, ensuring they grow in a healthy environment.

  • Versatility for All Planter Types: Whether you’re looking to waterproof new wooden planter boxes or restore old metal or concrete ones, Liquid Rubber adheres strongly to various materials, offering versatile protection for every type of planter box.

  • Easy Application Process: Liquid Rubber is designed for DIY enthusiasts and professionals alike. Its ease of application means you don't need specialized equipment or skills to achieve a professional-grade waterproofing for your planter boxes.

  • Cost-Effective Solution: By using Liquid Rubber, you can avoid the costly replacement of planter boxes due to water damage. A single liquid rubber application provides long-term protection, making it a smart investment for gardeners who value quality and longevity.

  • Enhanced Aesthetics: Beyond just protection, Liquid Rubber enhances the appearance of your planter boxes. It dries to a sleek, clean finish, helping to rejuvenate older planters and maintain the pristine look of new ones.

Transform Your Planter Box in 4 Simple Stages


Liquid Rubber provides an easy and effective way to waterproof planter boxes, ensuring long-lasting durability and protection for your plants. Follow these four simple stages for a watertight planter box.

Stage 1: Power Wash

  • Thorough Cleaning: Start by washing or water-blasting the entire surface of your planter box. This step is crucial for ensuring the best adhesion of the Liquid Rubber sealant.

Stage 2: Detailing for Precision

  • Sealant Application: Apply Liquid Rubber Waterproof Sealant with a brush to all seams, joints, and holes.

  • Geo-Textile Embedding: Embed pre-cut Geo-Textile in the sealant, making sure there are no air pockets or wrinkles.

  • Additional Protection: Extend the sealant application to any surface rust, pipes, and railing bases. Allow sufficient time for the sealant to cure.

Stage 3: Applying 2-3 Coats of Waterproof Sealant

  • Layering for Strength: Once the first layer is dry, apply 2-3 coats of Liquid Rubber Sealant using a brush, roller, or LRDIY spray machine.

  • Drying Time: Allow 24 hours between each coat for optimal results.

Stage 4: Final Protection and Backfilling

  • Curing is Key: It's crucial to let the Waterproof Sealant cure for 48-72 hours before proceeding.

  • Protection Board: After curing, apply a protection board (corflute) to safeguard the sealant.

  • Backfilling: Finally, backfill the planter box with soil, preparing it for planting.

  • Geo-Textile Preparation: Cut Geo-Textile to fit seams, joints, corners, and holes.

  • Initial Sealant Application: Apply Liquid Rubber Sealant before embedding the Geo-Textile. Ensure a smooth, wrinkle-free application.

  • First Sealant Coat: Apply an even coat of Liquid Rubber Sealant to the entire surface.

  • Rapid Cure Option: Use Rapid Cure Spray for a quicker setting, especially useful in unpredictable weather.

  • Second Coat Application: Apply a second coat of Liquid Rubber Sealant for enhanced waterproofing.

  • Recommended Thickness: Aim for a 1.5mm dry-film thickness for optimal protection.

  • Final Steps: Ensure the sealant is fully cured before applying the protection board and backfilling with soil.
